M Series probes are primarily used for moisture measurement, but
can be ordered to measure temperature as well. If ordered, an optional
temperature thermistor is included in the moisture probe and requires
an additional connection.
Use a four-wire shielded cable with a bayonet-type connector to
connect an M Series Probe to the electronics unit. The M Series Probe
may be located up to 600 meters (2000 feet) from the Series 1.
Before making electrical connections, connect the cable to the probe
by inserting the bayonet-type connector onto the probe and twisting
the shell clockwise until it snaps into a locked position
(approximately 1/8 inch of a turn). If you are not using a GE
Panametrics-supplied cable, refer to Figure 1-10 below to make
proper pin connections to a bayonet-type connector.

Figure 1-10: M Series Probe Cable Wiring Diagram
Use Table 1-2 on page 1-22 to connect the remaining end of the cable
to the terminal block labeled STD/TF PROBE on the back of the
electronics unit. See Figure 1-11 on page 1-22 for the terminal block
location. You must make all the connections listed in the table even if
you do not have the temperature option.
IMPORTANT: To maintain good contact at each terminal block and
to avoid damaging the pins on the connector, pull the
connector straight off (not at an angle), make cable
connections while the connector is away from the
unit, and push the connector straight on (not at an
angle) when the wiring is complete.
IMPORTANT: See the Calibration Data Sheets, shipped with the
probes, to connect the probes to their corresponding
channels. If a probe is connected to the wrong
channel, the meter will display incorrect data.
